Abstract
In producing CO.sub.2 from subterranean reservoirs at conditions apt to cause both aqueous and CO.sub.2 -rich liquid phases to flow in pipes conveying the fluid, the formation of hydrates is prevented by adding a specified type of inorganic electrolyte hydrate inhibitor in proportions capable of maintaining an effective concentration within the aqueous liquid phase.
